They are all about cheap manufacturing costs. If they are so easy to fracture is that a good thing?
All the talk about great for cap location? Never saw a problem with the old way of doing it, in normal every day use applications.
Cracked caps is nothing new, its been done long before auto engineers discovered it.
If a mechanic drops a rod or cap that have been separated from each other, and it lands on that rough cracked area, and there is a small imperfection to any of it, the parts are then junk.
The other not so cool thing is most all of them are made from sintered metal. Saying that is a good thing is like saying plastic is a great thing to use all over an engine, you know the famous Ford oil pans, the thermostat housings that break etc.
All these various parts made from junk materials are all talked up by the manufactures as something wonderful, but the real reason for their use is $ for the company not for you and I. The use of these materials just helps contribute to the planned obsolescence, and disposability of the over priced low quality engines they build.
